Metabolic profile of patients with isolated systolic hypertension.

Abstract

While hypertension is an important contributor to cardiovascular disease (CVD) and its treatment has well-established mortality benefits, there is uncertainty as regards the management of isolated systolic hypertension (ISH). Furthermore, the association of ISH with CVD and mortality has been established, but the metabolic characteristics of the affected population have not as yet been adequately described. The aim of this study was to describe the metabolic profiles of patients with ISH. An observational study of patients attending the Hypertension Unit of the University Hospital of Heraklion, Crete, Greece, was performed. In total, 809 hypertensive patients not on any antihypertensive treatment were identified. Among them, 44.7% were men, aged 55.6 ± 12.5years, while 29.7% of both men and women were smokers. Systolic blood pressure was 161.3 ± 15.8mmHg and diastolic blood pressure was 96.1 ± 11.3mmHg. Body mass index (BMI) was 31 ± 5.3kg/m2, while 9.6% had type 2 diabetes (T2D). A comparison of patients with ISH with those with hypertension, but not ISH, revealed that patients with ISH were older and had lower SBP and higher pulse pressure, while they also had lower total cholesterol and LDL and were more likely to have T2D, albeit they had a slightly lower BMI. On the other hand, they did not have any difference in terms of gender, smoking status, HDL, triglycerides, liver biochemistry, uric acid, or prevalence of impaired fasting glucose. Patients with ISH were older, with lower SBP, total cholesterol, and LDL and higher pulse pressure and higher prevalence of diabetes.
